fix: Ref transform being applied to variables named hasOwnProperty.

[aphex]

Given the variable var hasOwnProperty = Object.prototype.hasOwnProperty running through the transformer will result in

https://github.com/vuejs/vue-next/blob/master/packages/ref-transform/src/refTransform.ts#L313
id.name being hasOwnProperty which will return truthy for all objects. So instead we check for strict equality. We will only get properties flagged true in the scope passing through to be transformed.

This problem is blowing up all applications when using refTransform: true as @vue/shared is doing this exact thing here
https://github.com/vuejs/vue-next/blob/master/packages/shared/src/index.ts#L54

When running vite in dev mode the line below is being transformed to

var hasOwn = (val, key) => hasOwnProperty.value.call(val, key);

This small update will fix that.
